Patent CA-1120722-A (CA)
Inventor: LISS BARRY
IPC: C10J3/54

Abstract: Abstract of the Invention In the introduction of fresh carbonaceous particles into a fluid-bed reaction zone at injection velocities in excess of 20 ft/sec, a shroud gas is passed through a shroud passage on the injection nozzle at a velocity in excess of about 750 ft/sec, preferably at from about 1,000 to about 5,000 ft/sec, in sufficient quantities to supply a substantial portion of the overall energy input into the reaction zone for dispersion of the fresh particles and for breaking up of any agglomerates formed upon injection of the fresh particles into the reaction zone. By accommodating the agglomerating tendencies of the fresh feed material, the high energy shroud gas effectively contributes to the prevention of defluidization of the bed. The shroud gas may be inert or may comprise a gaseous reagent that reacts with the fresh carbonaceous particles in the reaction zone.  The energy supplied by the shroud gas desirably is at least about 80% of said energy input to the reaction zone.

Abstract: ABSTRACT OF THE DISCLOSURE            The quantity of salt required in brine regeneration of exhausted ion exchange resins is reduced by prescribed recycling.  Brine from a concentrator is passed onto and through a bed of ion exchange resin, and the initial discharge of spent brine from the bed is discarded.  Brine subsequently discharged from the resin bed is returned directly to the concentrator for reconcentration and reuse in like manner.  The resulting saving in amount of salt used lowers the regeneration cost and reduces the environmental impact inherent in wastage of chemical compositions.

Abstract: CORK EXTRACTOR                 Abstract of the Disclosure Apparatus for extracting a cork from a bottle com-prising a corkscrew rotatably mounted on a carrier, the carrier in turn being mounted for longitudinal reciprocation on a frame.  The apparatus further includes a control nut having a screw passage positioned to receive the corkscrew and con-figured to mate with the configuration of the corkscrew where-by, upon longitudinal movement of the corkscrew in the screw passage, rotational movement will be imparted to the corkscrew.          A latch, engageable and releasable independently of the force of gravity is provided for releasably latching the control nut to the frame to restrain relative longitudinal movement there-between.  Relative rotation between the control nut and the frame is also prevented.  A bottle-engaging assembly is con-nected to the frame for positioning a bottle with respect to the frame in longitudinal alignment with the screw passage.  The bottle-engaging assembly is associated with the latch and, when a bottle is engaged therein is operative cooperatively with the engaged bottle to release the latch.  The apparatus further comprises guide means laterally spaced from the corkscrew and cooperative between the frame and the carrier for guiding the latter in a longitudinal path.  Means are also provided for restricting rotation of the corkscrew as it is raised from the bottle with the cork.

Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus for processing a digital raster scan signal for use by an electrostatic printer having a print cartridge with an ion deposition matrix composed of sixteen drive electrodes intersected by 128 finger electrode is described.  A digital input signal, representing a line of raster scan data, is reformatted to be compatible with this print cartridge.  This is achieved by reformatting the signal into sixteen data groups, each containing 128 bits and storing at least sixteen data groups at any one time in a memory.  A motion control circuit responds to signals from the memory circuit, from the rotation of the drum and from paper sensors to effect scanning of the ion deposition matrix in a timed sequence.  One of the drive electrodes and all 128 finger electrodes are energised by one data group at any one time to effect ion deposition as the drum rotates, then the next drive electrode and the next data group are energised.  This is repeated until the entire matrix is scanned.  Since the ion deposition locations are offset from each other, sequential energisation as the drum rotates results in a single line of charge deposited on the drum corresponding to a line of an image represented by raster scan data.  In this way an electrostatic image is built up on the drum, and is then formed into a toner image which finally is transferred onto a copy material.

Abstract: ABSTRACT OF THE DISCLOSURE:           A method of sensing a position of a movable body by directly or indirectly converting a unit movement of the movable body into digital pulse signals and an apparatus therefore  A reference position is selected at a point, at which said movable body abuts against and presses a stopper provided at a specific position within the moving range thereof.  The purse signals are counted as the movable body moves from the stopper using the reference position as a reference number.  The coincidence of the number of the pulse signals counted with a first predetermined pulse number corresponding to a predetermined position is sensed so as to sense the fact that the movable body has reached a predetermined position and position sensing signals are emitted.  Further, as necessary, the position sensing signals that have been emitted are sustained for the duration of a second predetermined pulse number corresponding to a predetermined stroke preset so that the position sensing signals indicate that the movable body has reached the predetermined position and is within a predetermined stroke from the predetermined position.
